PLS HELP

Answers

Answer:

The slope of f(x) is equal to the slope of g(x). The y-intercept of f(x) is greater than the y-intercept of g(x).

Step-by-step explanation:

F(x) is already given to you on the graph. You need to plot the x and g(x) graph. (remember g(x) is just a fancy way of saying y)

Once this line is plotted, you will see that f(x) and g(x) are parallel to one another. G(x) is below f(x), so its y-intercept is lower.

Solve the simultaneous equations 2x + y = 5 and 2y = x – 10.

x = 4
The first equation can be substituted into the second one. It would be: 2(-2x+5)=x-10 and after solving it, x = 4

The given equations are :

[tex]2x + y = 5[/tex]

[tex]2y = x - 10[/tex]

From the first equation, we get :

[tex]2x + y = 5[/tex]

[tex]y = 5 - 2x[/tex]

What are ratio and proportion?

A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.

A rec center worker procures a similar sum every month. In the wake of laboring for a considerable length of time, he procured $4,500.

The amount of money that he earns each month is given as,

⇒ $4,500 / 3

⇒ $1,500 per month

Then the money he will make over a five-month period will be given as,

⇒ $1,500 x 5

⇒ $7,500

The money he will make over a five-month period will be $7,500.

Which one of the following would most likely have a positive linear correlation coefficient?
A. grade point average compared to the number of hours a student watches TV
B. the height of a tomato plant throughout the year
C. a person's salary compared to the amount of education they have attempted
D. SAT scores compared to hours spent studying

Answers

Answer: B

Step-by-step explanation: The tomato grows more over time so it will be a positive..

The height of a tomato plant throughout the year shows a positive linear correlation coefficient option (B) is correct.

What is correlation?

It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.

[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]

A. grade point average compared to the number of hours a student watches TV.

The grade points depend on the number of hours a student watches TV.

If watching time increases the grade point decreases.

B. the height of a tomato plant throughout the year

The height of a tomato and the number of years show a positive linear correlation.

C. a person's salary compared to the amount of education they have attempted:

The above situation represents an exponential regression.

D. SAT scores compared to hours spent studying

If the time spent in studying increases the SAT scores increases rapidly.

Thus, the height of a tomato plant throughout the year shows a positive linear correlation coefficient option (B) is correct.

Find the average speed in km/h for a journey of 175 meters and 35 seconds

Answers

Answer:

18 km/h

Step-by-step explanation:

1. Convert 175 metres into km

1000 m = 1 km (divide by 1000)

175 ÷ 1000 = 0.175 km

so 175 m = 0.175 km

2. Convert 35 seconds into hours

60 seconds = 1 min

60 mins = 1 hour

3600 (60 × 60) seconds = 1 hour (divide by 3600)

35 ÷ 3600 = 0.00972...

3. Calculate the speed

speed = distance ÷ time

= 0.175 ÷ 0.00972...

= 18 km/h

Jake earns $8 per hour for cutting grass. If he works a 35-hour week,
how much money will he earn?

Answers

There are many ways to solve these types of questions. But I am going to use the fraction method.

Step 1: Set up a fraction.

Setting up a fraction, given the question will be the units on the same level. And the money earned will be a variable, "[tex]m[/tex]". It does not matter whether they are top or bottom.

[tex]\frac{8}{1} = \frac{m}{35}[/tex]

Step 2: Solve

[tex]\frac{8}{1} = \frac{m}{35}[/tex]

Multiply 35 to both sides

[tex]\frac{35m}{35}=8\cdot \:35[/tex]

[tex]m=280[/tex]

Therefore, Jake will earn $280.

E. 54
( I really need this to be worked out so may I have help with this?)

Answers

Answer:

x = 9

y = 6

Step-by-step explanation:

Let's set up equations:

x + y = 15

x - y = 3

Let's rearrange one of these equations to use the substitution method:

x - y = 3

Add y to each side:

x = y + 3

Substitute in for x:

x + y = 15

y + 3 + y = 15

Combine like terms:

( y + y ) + 3 = 15

2y + 3 = 15

Subtract 3 from each side:

2y = 12

Divide each side by 2:

y = 6

Substitute this in to find the other variable:

x + y = 15

x + 6 = 15

Subtract 6 from each side:

x = 9

Find the x- and y-intercepts of : 4y-6x = 24

Answers

Answer:

x-intercept: (-4, 0)

y-intercept: (0, 6)

Step-by-step explanation:

4y - 6x = 24

To find the x-intercept, set the y value equal to 0.

4(0) - 6x = 24

Simplify by removing 4(0) since it just equals 0.

-6x = 24

Divide both sides of the equation by -6

x = -4

Since we set y equal to 0 and we know that the x value is -4, we can create a coordinate for the x-intercept of the equation.

(x, y) = (-4, 0)

Repeat the process for finding the y-intercept, but set x equal to 0.

4y - 6(0) = 24

4y - 0 = 24

4y = 24

Divide both sides of the equation by 4

y = 6

Write as a coordinate/intercept.

(x, y) = (0, 6)
